STRAP BUCKLE.

Application led July l6,

To all whom t may concern.'

Be it known that I, DANIEL FRANois DAL- 'roN, a citizen of the United States, residing at lVaterbury, county of N ew Haven, State of Connecticut, have invented certain new and useful Improvements in Strap Buckles, of which the following is a full, clear, and exact description.

This invention relates more particularly to buckles having a sliding plate which coacts with a fixed frame t0 grip and securely hold the strap in fixed position.

The principal object of the present invention is to improve this `type of buckle by rendering it more durable and attractive while maintaining its simplicity of construction.

Referring to the drawings forming part of this specification;

Fig. l is a plan view of thebuckle inverted;

Fig. 2 isa sectional view through the line 2-2 of Fig. 1;

Fig. 3 is a plan view of a modified form of buckle inverted;

Fig. 4 is a sectional view through the line 4-4 of Fig. 3;

Fig. 5 is a plan view of another modification of the buckle inverted; Y

Fig. 6 is a sectional View through the line 6-6 of Fig. 5; and l Fig. 7 is a sectional view of the buckle shown in connection with the strap or belt.

The buckle comprises a fixed member or frame A and a clutch slide-plate B. The frame comprises two side bars 1--1 and transverse bars 2-3. A third transverse bar 4 is also shown which may be employed if` desired, the three bars being connected to the side bars 1--17 thereby forming front and rear slots 5 and 6 respectively for the reception of the strap C (see Fig. 7). Flanges 7-7 are formed on the outer edges of the side bars and turned over to form oppositely disposed guide-ways 8-8.

The clutch slide-plate comprises two side bars 9-9 slidably engaged by the guideways 8-8, and in the form here shown the ways are constructed of sufiicient length to retain the sides of the plate entirely throughout their lengths in any positionfof the plate relative to the frame. `Two transverse bars 10 and 11 are connectedto the side bars 9 of the plate to form a slot 12 for the recep- 1 tion of the strap which is dis-posed to reg- 1923. Serial No. 649,791.

ister with the slot 5 in the frame when the plate is in retracted position to form an open slot entirely through the buckle of suiicient width to receive the strap.

A flange 13 is formed on tne front of the plate B and is folded tightly over upon the. plate to form a rounded front edge 'i4 and a reinforced front wall of double thickness, the folded flange is turned up to form a lip 15 projecting from the front of the slot 12. As is obvious both the frame A and slide-plate B may be stamped from sheet metal and suit-ably folded to form the'y parts above described. The buckle is manipulated in securing and releasing the strap C in a similar manner to the buckle shown in the patent to Kerngood No. 1,049,732, which operation is common to all buckles of this type and therefore no further description thereof is considered necessary here.

While in Figs. 3 and 4 the transverse bar 4 is used for securing the buckle to the garment, in the form of buckle shown in Figs. 1, 2, 5, 6, and 7 a transverse bar 16 is Vprovided for attaching the buckle to the garment. This bar is raised from the frame as clearly shown in Fig. 2 and has its ends somewhat enlarged and bent to form right angles, the free legs or ends 17 being formed with openings 18. These ends 17 are held firmly in the ways 8 by bending or setting the metal of the flanges into the openings 18 as shown yat 19 Fig. 2. The plate B is arrested in its forward and rearward movements in the forms of buckles here shown by (3o-acting means forming part of the plate and part of the frame respectively. For this purpose, in the form of buckle shown in Fig. 1 the attaching bar 16 is considered part of the frame and is suitably positioned to form a stop for the plate B so that when it reaches its rearward position the rear end of the plate will strike the ends of the bar within the ways 8 which will take place when the slots 5 and 12 are in registering positions as already described.` To stop the plate at its extreme forward posi-v tion the lip 15 is provided with end extensions 2O projecting laterally beyond the folded fiange, and the forward ends of the flanges 7 are provided with lugs 21 projecting toward each other in the path of the respective ends 2O to co-act therewith to stop the plate at said forward position. 1n Figs. 3 to 6 inclusive a different construction is shown for stopping the plate in its forward and rearward movements. In this form of buckle the side flanges 7 7 are cut to form oppositely disposed slots 22 and the plate is provided with oppositely disposed lugs 23 which are engaged by the slots 22. The lugs 23 will strike the end walls of the slots as the plate is moved back and forth and the slots are made of suitable length so that the lugs 23 will strike the end walls of the slot as the plate reaches its extreme forward and rearward movements. The style of buckle shown in Figs. 5 and 6 is a combination of the buckles shown in the other views. In this form of buckle the attachingbar 16 of Figs. l and 2 is employed, and the stopping means comprising the slots 22 and lugs 23 of Figs. 3 and 4- is employed.

IVhen the buckle of the several forms here shown is in position for use, that is to say right side up, as shown in F ig. 7, the stopping means for the plate B is concealed from View, entirely so in Figs. l and 2 andL substantially so in the other form of buckle shown in the other views thereby presenting a very neat and attractive appearance. Moreover the rounding edge 14 of the folded front portion of the plate provides a smooth surface admirably adapted to serve as a finger piece when it is desired to force the plate back, and for this purpose the rounded folded end may project as far as desired beyond the frame in its forward position. The folded-over front portion of the plate gives additional strength and rigidity and adds to the durability of the buckle.

Having thus described my invention what I claim and desire to protect by Letters Patent is z- 1. In a strap buckle, a frame comprising two side bars, three transverse bars con-v nected to the side bars to form front and rear slots for the reception of the strap, anges formed on the outer edges of the side bars turned over to form oppositely disposed guide-ways, a clutch slide-plate comprising two side bars slidably engaged by the ways, the ways being of sufieient length to retain the sides of the plate throughout their entire lengths in any position of the plate relative to the frame, two transverse bars connected to the side bars of the plate to form a slot for the reception of the strap disposed to register with the front slot in the frame when in retracted position, a flange extending from the front edge of the plate folded upon the plate to form a rounded front edge and a reinforced front wall of double thickness, a lip projecting from the edge of the folded flange at the front of the slot formed in the plate, and means forming part of the plate and frame respectively adapted to co-act to arrest the forward and rearward movements of the plate.

5. In a strap buckle, a frame comprising two side bars, transverse bars connected to the side bars to form a slot for the reception of the strap, flanges formed on the outer edges of the side bars turned over to form oppositely dispose-d guide-ways, a bar for attaching the buckle having its ends secured in the respective guidesways, a clutch slide-plate comprising two side bars slidably engaged by the ways and adapted to strike the said secured bar to arrest its rearward movement, a flange extending from the front edge of the plate folded upon the plete to form e rounding front edge and a reinforced wall of double thickness, a lip projecting from the edge of the flange at the front of the slot Jformed in the plete and having its ends extending laterally bel0 yond the folded flange, and lugs projecting toward each other from the forwardr end of the side flanges in the path of the respective extending ends of the lip to coact therewith to stop the plate at its extreme forward movement.
